The aim of this study was to analyze clinical importance of exhaled nitric oxide (NOex) measurement for early detection, differential diagnosis and control of treatment of chronic respiratory pathology in children. The study involved 412 children of 5 to 18 years old with different chronic bronchopulmonary diseases. Apart from a typical clinical, laboratory, and instrumental diagnostic methods, NOex was measured in all the children using the chemiluminescent gas analyzer 280i (Sievers, USA). The control group included 30 healthy children aged 5 to 18 with mean NOex 14.8 ± 1.4 ррb (9.2 ÷ 21.4 ррb). The majority of asthmatic children had high NOex (> 20 ppb in 284 (90 %) asthmatic children), р < 0.01, both in stable asthma and exacerbation. The NOex level was directly correlated to the severity and period of the disease (frequency of asthma attacks, time from the last asthma attack, lung function parameters), and blood levels of allergic markers (eosinophils, total IgE, circulating immune complexes, IL-4). Therefore, NOex monitoring was useful in evaluating the efficacy of different treatment modes. In other chronic respiratory diseases, NOex level was also elevated but to lesser degree. In children with primary ciliary dyskinesia, NOex was significantly below the normal level that could be used as a preliminary screening tool. In conclusion, NOex measurement is a reliable and objective method to control allergic inflammation in the airways. It is of great clinical importance and is helpful in differential diagnosis of chronic respiratory diseases and confirmation of the diagnosis. It allows individual choice of therapy, control of the patient's adherence to treatment and prognosis of future exacerbations.

The changing states of T cell populations responsible for the chronic course of allergic inflammation and diseases, including allergic bronchial asthma, are not yet sufficiently characterized. The aim of this study was to detect phenotypic changes in the CD45RA/CD45RO positive T lymphocytes and the level of regulatory cytokines (TNFα, IFNγ, IL-4, IL-6, IL-8, IL-10, IL-13, IL-17А, IL-17F) in allergic respiratory diseases (ARD) in children. In blood of 90 children aged 3-11 (60 children with ARD and 30 healthy peers) were studied of the immune cellular populations and cytokine indices. The levels of IL-4, IL-8, IL-10, IL-13, IL-17A and IL-17F in blood serum of children with bronchial asthma and allergic rhinitis differed from appropriate indices in control group (p = 0.001). The quantity of CD3+CD8+CD45RACD45RO+ cells, T helpers (p < 0.05) and Th effectors simultaneously expressing both isoforms of the CD45RA+ and CD45RO receptor in peripheral blood of children with ARD significantly exceeded those in control group (p < 0.001). In healthy children, Th17 population (CD3+CD4+CD196 lymphocytes) comprised 9.49±1.6% of CD3+CD4+ of cells, the number of such lymphocytes was significantly increased to 14.5±0.77 in children with allergic diseases (p < 0.001). Absolute numbers of Th17+ cells were 93.0±9.30 and 127,0±72.0 cells/µl respectively (p = 0.002). Indicators of CD4CD45RO positive memory cells in children with ARD was determined as significantly lower (p < 0.001), whereas quantity of CD3+CD19+ proved to be higher (p < 0.05) than in healthy peers. Absolute counts of these cells did not differ between the groups. The number of CD8+CD45RO+T lymphocytes was significantly higher in children with allergic diseases (p < 0.025). This research shows that the quantitative ratio of CD3+CD8+CD45RA+ and CD3+CD8+CD45RO+ populations of T cells, and increased levels of cytokines, synthesizable via Th2 and Th17, in peripheral blood may be helpful for understanding genesis of allergic respiratory diseases, and extends our knowledge on immune mechanisms of allergic disorders for individualization of therapeutic programs.

<i>Introduction:</i> Chronic abdominal pain in children is a very frequent and sometimes challenging diagnostic issue. Differential diagnosis in that cases is difficult and often connected with numerous, time-consuming, expensive, and frequently stressful diagnostic studies. The aim of the study was to establish whether fecal calprotectin concentration (FCC) and TNF-alpha may be useful in children with chronic abdominal pain to differentiate between inflammatory bowel disease (IBD), other inflammatory gastrointestinal disorders, and functional gastrointestinal disorders. Methods. The study included patients (median age 13 years), who were assigned to functional gastrointestinal disorders group (n=33); inflammatory gastrointestinal disorders other than IBD (n=71), children with IBD (n=37) and 22 healthy children served as a control group. The concertation of FCC and TNF-alpha in stool samples was measured using ELISA. <i>Results:</i> In healthy children and in children with functional disorders FCCs were below 100 μg/g. In patients with IBD FCCs and TNF-alpha were markedly elevated as compare to children with functional gastrointestinal disorders, however using ROC discrimination of IBD patients was significantly better using FCC than TNF-alpha. <i>Conclusion:</i> FCC is better test for differentiation between IBD, other inflammatory gastrointestinal disorders, and functional gastrointestinal disorders as compare to TNF-alpha concentration in stool. FCC as screening test in patients with chronic abdominal pain should allow to diminish unnecessary diagnostic in cases of functional gastrointestinal disorders.

Aim. To study the number of neutrophils in the oral cavity, their bactericidal potential, to assess as an indicator for predicting the course of recurrent bronchitis (J40) and community-acquired focal pneumonia in children. Methods. 87 children between 5 and 10 years old, including 52 children with recurrent bronchitis and 35 with focal community-acquired pneumonia were observed. The control group consisted of 37 conditionally healthy children of a similar age. Viral antigens were studied by chemiluminescence immunoassay. Oral neutrophil counts and functional activity were determined. Antibacterial antibodies were measured by an enzyme-linked immunosorbent assay (ELISA). Results. 70.11% of patients had a viral antigen, and 57.47% had immunoglobulins M and G against bacterial pathogens. Oral neutrophil counts increased in the main group compared to the control group: up to 163.826.5 cells (p 0.001) in recurrent bronchitis, to 110.925.5 (p 0.05) in community-acquired pneumonia. By the recovery period, the number of oral neutrophils counts decreased in recurrent bronchitis (1.7 times higher compared to the control group, p 0.01) and remained practically unchanged in community-acquired pneumonia (115.026.9, p 0.05). Myeloperoxidase level had opposite changes for the groups compared to the control group: with recurrent bronchitis, it was 1.610.09 to the level in the control group (p 0.05), with community-acquired pneumonia 0.730.09 to the level in the control group (p 0.001). The level of lysosomal cationic proteins decreased to 0.770.09 to the level in the control group (p 0.05) in recurrent bronchitis, and to 0.800.09 (p 0.05) in pneumonia. Conclusion. In inflammation of the respiratory tract, neutrophil migration to the oral cavity, as well as myeloperoxidase level, increases, indicators of spontaneous luminol-dependent chemiluminescence are activated, and a deficiency of lysosomal cationic proteins occurs; this prevents the penetration of the pathogen into the lower respiratory tract.

Background: There are not enough studies and evidenced researches conducted related to this topic. Therefore, we studied fetal haemoglobin in various somatic diseases in children with sensorineural hearing loss associated with hepatitis B. Materials and Methods: 26 children with sensorineural hearing loss associated with hepatitis B, aged from 5 to 18 years, were examined. The comparison group consisted of 8 children with sensorineural hearing loss without concomitant somatic pathology. The control group consisted of 12 healthy children. The compulsory examination plan for patients included generally accepted laboratory and instrumental diagnostic methods: complete blood count, urine, feces, Wasserman reaction, ECG. Results: Hb concentration in blood inpatient children with sensorineural hearing loss of the associated chronic hepatitis B (CHB) was reduced significantly by 58% compared with the healthy children. In children with Sensorineural Hearing Loss (CHT) without CHB, the studied parameter decreased when compared with healthy children by 25%. Analysis of the results showed a significant increase in the level of fetal haemoglobin in the blood of children with CHT associated with hepatitis B on average by 1.5 times, indicating hypoxia. Conclusion: Dependence of the indices of partial oxygen in the blood and, to a greater extent, HbF, on the blood content of the vasoconstrictor endothelin-1, von Willebrand factor, indicates the pathogenetic significance of the leading markers of endothelial dysfunction in the development of tissue hypoxia in children with sensorineural hearing loss combined liver disease.

Перинатальная патология центральной нервной системы занимает ведущие позиции в структуре детской заболеваемости, что диктует необходимость поиска оптимальных подходов к ранней диагностике гипоксически-ишемических и травматических поражений центральной нервной системы, в том числе с использованием технологий математического моделирования. Цель работы состоит в создании и апробации математической модели дифференциальной диагностики гипоксически-ишемических и травматических поражений нервной системы у детей с использованием метода кариометрии. В исследование были включены 290 доношенных детей первого года жизни: первая группа сравнения включала 120 новорожденных с гипоксически-ишемическим поражением центральной нрвной системы, вторая – 120 новорожденных с ее травматическим поражением, контрольная группа включала 50 здоровых детей. Всем детям в возрасте 1, 3, 6, 9 месяцев и 1 года оценивались физическое и нервно-психическое развитие, двигательные функции по методу Л. Т. Журбы. На первом месяце жизни проводились нейросонография головного мозга, рентгенологическое обследование головы и шейного отдела позвоночника в двух проекциях. В возрасте 1, 3 и 6 месяцев выполнялось морфологическое исследование лимфоцитов (кариометрия). Для создания математической модели дифференциальной диагностики гипоксически-ишемических и травматических поражений нервной системы были взяты 12 показателей нейросонографии и 4 показателя морфологии лимфоцитов периферической капиллярной крови (площадь и периметр ядра, площадь и периметр клетки). В построении диагностической модели использовали самообучающуюся искусственную нейронную сеть, работа которой воспроизведена при помощи созданного программного приложения. Исследование показало, что полученная нами модель проста в использовании, экономит время на постановку диагноза, обладает высокой степенью распознавания: специфичность модели – 89,2%, чувствительность 92%. Perinatal pathology of the Central nervous system (CNS) occupies a leading position in the structure of childhood morbidity, which dictates the need to find optimal approaches to the early diagnosis of hypoxic-ischemic and traumatic CNS lesions, including using mathematical modeling technologies. Objective: to create and test a mathematical model for differential diagnosis of hypoxic-ischemic and traumatic lesions of the nervous system in children using the karyometry method. The study included 290 full-term infants of the first year of life: the first comparison group included 120 newborns with hypoxic – ischemic CNS damage, the second group-120 newborns with traumatic CNS damage, the control group included 50 healthy children. All children aged 1, 3, 6, 9 months and 1 year were evaluated for physical and neuropsychic development, motor functions according to the method of L. T. Zhurba. In the first month of life, neurosonography of the brain, x-ray examination of the head and cervical spine in two projections were performed. Morphological examination of lymphocytes (karyometry) was performed at the ages of 1, 3 and 6 months. To create a mathematical model for differential diagnosis of hypoxic-ischemic and traumatic lesions of the nervous system, 12 indicators of neurosonography and 4 indicators of peripheral capillary blood lymphocyte morphology (area and perimeter of the nucleus, area and perimeter of the cell) were taken. A self-learning artificial neural network was used in the construction of the diagnostic model, the operation of which was reproduced using the created software application. The study showed that the model we obtained is easy to use, saves time for diagnosis, and has a high degree of recognition: the model specificity is 89,2%, and the sensitivity is 92%.

SUMMARY OBJECTIVE To investigate the relations of T lymphocytes, cytokines, immunoglobulin E, and nitric oxide with otitis media with effusion (OME) in children and their clinical significances. METHODS Fifty children with OME treated in our hospital were enrolled in the study (observation group). Fifty healthy children were selected as control. The percentages of CD4+ and CD8+ T lymphocyte and CD4+/CD8+ ratio in peripheral blood, and the levels of cytokine (IL)-2, IL-4, IL-6, immunoglobulin E (IgE) and nitric oxide (NO) in peripheral blood and middle ear effusion (MEE) in both groups were detected. The correlations of these indexes with OME were analyzed. RESULTS The percentage of peripheral blood CD4+ and CD8+ levels, CD4+/CD8 ratio, IgE, and NO levels in the observation group were significantly higher than those in the control group (P < 0.01). In the observation group, the IL-2 and IL-6 levels, and IgE and NO levels in the MEE were significantly higher than those in peripheral blood (P < 0.01). In addition, in the observation group, the MEE IL-2 and IL-6 levels were positively correlated with peripheral blood CD4+/CD8+ ratio, respectively r = 0.366, P = 0.009; r = 0.334, P = 0.018. CONCLUSIONS The levels of peripheral blood CD4+ and CD8+ lymphocytes and MEE IL-2, IL-6, IgE, and NO levels are increased in children with OME. These indexes have provided significant clues for the diagnosis of OME in children.

The aim of the research was to study the phenotype of eosinophils in children with atopic bronchial asthma and their role as diagnostic criteria of the disease. Materials and methods. We have examined 130 children aged from 6 to 18 years old with atopic bronchial asthma. The control group consisted of 40 healthy children from 6 to 18 years old, who didn’t have allergic diseases. During the research the relative and absolute levels of eosinophils, the level of eosinophils carrying FcεRI and FcεRII (CD23) – receptors were established. Results. The relative level of eosinophils in asthmatic children was 6.00% [3.00; 8.00], the absolute level – 417.00 cells/μL [232.00; 636,00], which is significantly higher compared to control group, where the relative level was 2.50% [1.00; 3.00%] and the absolute level was 166.50 cells/μl [86.00; 213.00] (p&lt;0.001). The level of eosinophils carrying the FcεRI receptor was 420,00 cells/μl [250,00; 660,00], which is significantly higher than in the control group – 200,00 cells/μl [140,00; 240.00] (p&lt;0.001). The relative level of eosinophils carrying CD23 receptor on their surface was 62.20% [35.40; 76.60] and the absolute level –223.37 cells/μl [105.30; 375.24]. The results are significantly higher than those of the control group: 25.45% [14.30; 30,60] (p&lt;0,001), and 30,88 cells/μl [25,63; 42.84] (p &lt;0.0001) respectively. It was found in the ROC-analysis that there is high evidence of presence of atopic bronchial asthma if absolute levels of eosinophils carrying CD23 receptor was 73.008 cells/μl or more or the relative index – 35.10% and more. Conclusions. The relative and absolute levels of eosinophils, as well as eosinophils carrying FcεRI and CD23 receptors are statistically significantly higher in atopic bronchial asthma than in control group patients. Increased number or relative index (73.008 cells/μl or ≥ 35.10% respectively) of eosinophils carrying CD 23 receptors can be considered as a diagnostic criterion of atopic bronchial asthma.

Purpose of the Study: Assessment of the influence of the type of the adapted infant milk formula in infants on the formation of the body resistance. Children Characteristics and Study Methods. 105 virtually healthy children were examined, as follows: 35 children were breastfed (control group), 70 children were formula fed including 35 children that received NENNY with prebiotics formula based on the goat milk (main group), 35 children – formulas based on the cow milk with probiotics and prebiotics (comparison group). The incidence rate of the acute respiratory diseases (ARD) as well as the number of the pneumonia histories in the infants were assessed, and the body resistance index was calculated. The laboratory assessment of the child body immunoresistance was carried out using the method of imprint smears from the nasal mucous membranes and the method of nasal washes. Results. It was determined that there were 2 times more children of the main group with no history of the acute respiratory diseases when infant than in the comparison group. In general, the good resistance (were sick 0-3 times a year) in the main group was registered in 82.9% of the children, while it was only 60% in the comparison group. The average number of the ARD cases per year was 2.3 ± 0.02 in the main group, which is 1.5 times less than in the comparison group – 3.6 ± 0.04 (p <0.05), and in 1, 3 times more than that in the control group – 1.8 + 0.03 (p<0.05). In average, the resistance index was 0.28 ± 0.02 in the main group, while it was 0.36 ± 0.03 in the comparison group, and 0.25 ± 0.02 in the control group. When studying the incidence rate of the community-acquired pneumonia in the infants, it was revealed that 2.8% of them were ill in the control group, 5.7% of them in the main group, and 8.5% in the comparison group. When feeding the child with formulas based on the goat’s milk, the level of mucosal immunity of the nasal mucosa and enzyme systems of the intraleukocyte microbicidal system is assured, which is virtually indistinguishable from the level of immunity achieved with breastfeeding. Conclusion. Adapted NENNY with prebiotics formulas can be recommended for children who are formula fed when infant in order to increase the body’s resistance and to reduce the incidence rate of the acute respiratory diseases and community-acquired pneumonia.
